I get a segfault (gnu/linux) when the number of the inactive instances to free in `orcompact' (insert.c) overcomes a limit. This limit is 6 on amd64 (6 core), for example (with your orc file): i 1 1 2 22 75.81943 0 0 0 0 1 1 i 1 1 2 22 75.81943 0 0 0 0 1 1 i 1 1 2 22 75.81943 0 0 0 0 1 1 i 1 1 2 22 75.81943 0 0 0 0 1 1 i 1 1 2 22 75.81943 0 0 0 0 1 1 i 1 1 2 22 75.81943 0 0 0 0 1 1 ; i 1 1 2 22 75.81943 0 0 0 0 1 1 ; crash s 5.000 e 5.000 works but it crashes if I add another i-statement. The limit depends on the machine, for example it is 11 on a old pentium3. In bytes the limit is 48 on 64bit machine and 44 for 32bit machine. I don't know yet if it is a coincidence. The trigger for a segfault with your code is s ; with or without time (so memory free in orcompact after this) ? time ; whatever statement with time tito ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Csound-devel mailing list Csound-devel@lists.sourceforge.net
